there are whole blocks of them erected or with the builders hard at work turning another roof-top into the floor of still another shop. It is plain that the present output is going to do some tall climbing very soon. I find that my available space is running short, while I have still left untold much that I have seen, so I must be content to assure the Front that I have covered the ground of munition work more fully than these writings may indicate. I don’t think I left any department of the work untouched. I saw the making of bombs and grenades and air-torpedoes, trench-mortars and bomb-throwers--cheerful things some of these too, throwing bombs and winged torpedoes of impressive size with accuracy for hundreds of yards--shells, innumerable shells, from the pill, standing man-high and measuring about four feet round the waist, that “Granny” throws, down through all the sizes of the twelve-inch, and of “Mother’s” fit, to the fodder for the ubiquitous 18-pounders and Four-point-five “hows,” and still down to the fancy sizes for the anti-aircraft and the pretty little one-pounder pom-poms. I saw all shapes and sizes of guns too--massive, lengthy monsters in stages running from the huge rough castings to the smooth shining and polished tubes, fat-bodied squat howitzers, and, laid out in rows, many field-guns, and, ranked in battery upon battery, many more light Q.F. and machine-guns. There was an aeroplane factory where at least a score of ’planes stood in various stages, from one completely built and ready for her engines, to those still only in dismembered finished parts, to say nothing of the piles of parts in the making. Here alone the one firm I should have supposed were turning out more finished ’planes per week--battle-’planes and observing-’planes and fast-flying scout-’planes--than all our armies could find a use for; and yet there are, even to my own knowledge, several other ’plane factories. So that you may take it I have made a full and comprehensive round, have satisfied myself in order that I might fully satisfy the Front that all their munition wants are going to be satisfied up to and over the hilt. I can only finish the report of my observations with the same assurance as I began it--we are never going to be short of munitions again; spend them as fast and hot and heavy as we can, the workshops can make faster than the Front can use; and the longer the War runs the more completely we shall be armed and equipped to wage it. All this seems certain and positive if--it is the only “if,” although it might be a big one--_if_ the war-workers continue to do their share, _if_ they play up and back us in playing out the game.
